Nacht der Untoten
the first one. one building, no perks, no power, and one song that arrived late.
the first zombies map has no quest and nothing to build, and that is the map rather than a gap. it does have one hidden song, `Undone`, and even that is not really this map's: it was added years later in the Black Ops re-release, three years after the World at War original this page is dated to.
